1. A hand dryer configured to accept multiple voltage inputs, the hand dryer comprising:

  • a blower vacuum motor for producing output air;

    a heating element for heating the output air, the heating element comprising a plurality of resistors configured to form a plurality of resistive circuits, each of the plurality of resistive circuits in one of series and parallel with the blower vacuum motor; and

    a voltage controller for selecting a nominal voltage supplied to the blower vacuum motor via the plurality of resistors of the heating element, the voltage controller selecting the nominal voltage based on an input voltage by operating one or more relays to independently select one of the plurality of resistive circuits.
